does any one know how the level up system works because I pressed the button with the plus symbol and all it does is explain level up then just gives a leave button
You need at least 5 lvl points to increase a stat. You get only one lvl point per level up so you need 5 levels to increase a single stat by 1.
You can earn more lvl points by completing diffifult bosses, story progression or beat dungeons and exchange Adv. Pouints into lvl points.
